Metra 70-1677-1 Wire Harness
1988 Chevrolet Corvette
Crutchfield Customer Review (What's this?)
This wiring harness adapter is OK with one minor fault. It's a 12 pin connector with only 11 pins installed. They decided not to install a pin for the dash light dimmer circuit. When I emailed to inquire about this I was told that it wasn't needed. That's mighty presumptuous. How do they know I don't need this connection? Saving a few cents by omitting one of the connections without mentioning it on the website is wrong. Anyway, I bought a second wiring harness adapter from another vendor and it included all 12 connections. Now I can install my new system.
